City Models

3D city models are used worldwide for arange of applications by an array of users.  The breadth of applications that are available highlights the virtual city as a powerful tool for an organisation and can be used at strategic, tactical and operational levels of a project.  If used correctly, a virtual city model can provide a more co-operative approach to planning and modelling.
 
Hosting
A major decision that faces institutions who establish or commission a virtual city model is the issue of hosting the model and its data.  Issues for consideration include:
  • data collection and management;
  • legal rights to the data;
  • project cost and funding;
  • facilities, applications and end users.
Various stakeholders and participants (see applications) can have both financial and specialist contribution to a virtual city project.  A model that has been commissioned by a city council, for example, may require specialist city modellers to maintain and update the data, based on a license agreement between the stakeholders.
